The storm is expected to stretch from Colorado to Maine and warnings are in place in 14 states.
Some places are predicted to see as much as two feet (60cm) of snow.
The National Weather Service (NWS) has warned of “dangerous, if not impossible travel conditions and isolated power surges” in the worst affected areas.
The heaviest snow is predicted to fall on Wednesday evening. The NWS said some areas will see more snow “in one event than they have seen all of last winter”.
At least two people have died in Pennsylvania following a multi-car crash on the Interstate 80 in Clinton County. Police said multiple people were injured in the crash which involved between 30-60 vehicles.

He warned residents to “take this seriously”.
Schools across the city have moved to online learning, outdoor dining has been suspended and ferry routes in the city have stopped.
Hundreds of flights have been cancelled and rail services suspended across the northeast.
US Secretary for Transportation Elaine Chao warned those in the path of the storm “to know that’s expected for your area and don’t drive in dangerous conditions”.
